Zusammenfassung:	A sintered bearing contains 3-12 weight percent of aluminum and 0.05-0.5 weight percent of phosphorus, has copper as the balance of the main components, and contains unavoidable impurities. The sintered bearing 1 is characterized by having a structure in which an aluminum-copper alloy is sintered using a sintering agent added to a starting material powder, and in that pores (db, do) in a front layer section of the sintered bearing 1 are formed smaller than internal pores di.
